A shut-off valve for a hydraulic system for an aircraft, which system includes a brake operation device, a pressure supply, a reservoir, the shut-off valve, and a wheel brake. The shut-off valve (20) is in fluid communication with and is disposed between the pressure supply and the brake valve. The shut-off valve includes a poppet (158), a first valve seat (182) and a second valve seat (190) . Movement of the poppet is controlled by operation of the brake operation device. The poppet is movable between a first position where the poppet acts against the first valve seat and a second position where the poppet acts against the second valve seat. In the first position, fluid flow is blocked between the pressure supply and the brake valve through the shut-off valve. In the second position, fluid flow is allowed between the pressure supply and the brake valve through the shut-off valve. The wheel brake is in fluid communication with and downstream from the shut-off valve.
